Congratulations, David.
A great day, I still remember my first flight - how can
you forget it {:>)?. I found that with my fixed pitch prop that approx
120 IAS mph climbout produced the best cruise rate of climb with the best
cooling. Steeper climb made both the ROC and Temps
increase. After take off with maximum power (and heat) and minium
cooling air due to low airspeed and angle of attack is generally the toughest
scenario for cooling. So be interesting to see what you get
when you get it up and leveled off for cruise.
Great work and other RV-6 rotary joins the
line.

Subject: [FlyRotary] N655HC FIRST FLIGHT.
Short flight, seasoned fighter/experimental RV8 builder test pilot, twice
around the patch, 5950 RPM, coolant went to 220F on climb out, oil was at 210F,
78F OAT, temps climbed a little higher, powered back & setup for
landing. This is an RV6A Rotary, five years in the making, 13B Bruce T.
aircraft modified eng., 2.17 RWS drive, EC2, EM2, Ivoprop Magnum 65-105 deg.
elect. in-flight adjust., Hushpower res./muffler, intake similar to Tracy's RV4
before the Ren. eng., my own Dynamic chamber, 3" throttle body. I do
currently have a 180F therm. installed, might try removing to look for
lower temp. #s, Then louvers in bottom of lower cowl, need more flight tests,
cowl & coolers & inlets are very similar to Ed Anderson's RV6A
Rotary, thanks Ed, Bill E., Tracy C., Dave L., & all
the folks on THE LIST. David R. Cook RV6A Rotary
